Glamorgan (Morgannwg in Welsh) is a traditional county in South Wales. The county council was abolished in 1974; it was subdivided administratively into West Glamorgan, Mid Glamorgan and South Glamorgan until 1995 and was then further subdivided, meaning the county is now administered by a number of highway authorities.

Geography & Economy

The A4232 crosses the River Taff to Cardiff Bay

Glamorgan is Wales's southernmost county. It runs from the Brecon Beacons National Park in the north to the Bristol Channel coast in the south and west-east between the Rivers Loughor and Rhymney. The north of the county consists of the well-known Welsh Valleys, one of the most built-up mountainous areas in the UK, whilst further south the land flattens out into the largely agricultural Vale of Glamorgan. Much of the coast is built-up and indeed industrial, although places like Barry and Penarth are seaside resorts. Glamorgan's best known industry is coal - at one time this covered virtually the whole county and Barry was the world's largest coal port - but this has now gone. Other heavy industries in the county include copper in Swansea and ferrous metals, particularly in Port Talbot; this last-named is still in existence. The decline of traditional industries has led to the need for diversification. For example, Swansea is now home of the DVLA whilst Llantristant, in the east of the county, contains the Royal Mint. The county town of Cardiff was declared capital of Wales in 1955 and contains a number of national institutions such as the National Museum of Wales and the National Assembly.

Roads

The M4 near Port Talbot

Roads in Glamorgan are constrained by the terrain giving the county a fragmented network. In the flat Vale of Glamorgan the sparse population means that there is no need for a large number of roads, whilst in the mountainous rest of the county roads are forced to run along the valleys rather than across, although there are a few exceptions. The county's main east-west roads are the A465 Heads of the Valleys Road and the A48 and M4 along the coast. The South Wales Trunk Road Agent maintains the county's trunk roads, which include the A465 and M4, as well as the main north-south A470, the A4060 through Merthyr Tydfil and part of the A4232 towards Cardiff. Non-trunk roads are split between 7 highways authorities: Bridgend CBC, Caerphilly CBC, City of Cardiff Council, Merthyr Tydfil CBC, Neath Port Talbot CBC, Rhondda Cynon Taf CBC, City and County of Swansea Council and Vale of Glamorgan Council.
